I liked this prologue very much. But I'm glad it wasn't the prologue in the book because while I liked getting to know Jace a bit more, I liked the way he was portrayed in the published story even better. Also, Jace seemed a bit different in the published version than what the deleted prologue offered not just because he was more mysterious but also because some details he gave in the deleted prologue about the Clave and his past seemed different than what was actually in the book.
Now this one just made me so curious! I suppose I'll have to read The Infernal Devices series
to truly understand what this was all about.
I swear Jace is going to break my heart. He hides his emotions wells but oh, man, are his POVs going to be intense if they continue to be anything like this one!
